Eryngium planum Blue Cap


Sea Holly

USDA Zone: 2-9

Plant number: 1.205.200


(='Blaukappe') Sea Holly features open umbels of prickly steel-blue flowers, which are a favourite for cutting, fresh or dried. This is a very hardy species, small flowered but with superb colour in the garden, especially nice contrasting with yellow or gold neighbours. Plants spread to form a small patch. Easily divided in early spring. Tolerant of hot, dry sites, and soils high in salts. For drying, pick stems just as the flower clusters open fully, and hang upside down to dry in a warm, dark place. Attractive to butterflies.
